turn radio on and unplug speakers one at a time if the problem goes away once you unplug a particular speaker, then there lies the problem. it sounds like you have a short. Unplug the rca's going to your amp one at a time also.

Protect
occurs when 1 or more of your speaker wires is touching somewhere.
Power off the receiver, connect speaker wires to receiver and speakers
again, power back on, should fix the issue.

Protet mode is a special diagnostic mode that starts when a fault is detected.

When in protection mode the unit is prevented from starting by protection circuit, so to prevent further damage.

Check the speakers and speakers wiring, a contact in speaker wires, or faulty speakers can send the unit in protection.

Try
unplugging power cable for one hour or so. then connect cable back and
see if you get rid of protect state. Sometimes accumulation of
electrostatic charges inside circuit capacitors can kick in protect
mode. In that case unplugging the unit from main for some times can get
rid of electrostatic charges, and reset circuits by draining power
completely.If that was the problem, you will not get Protect when plugging back power cable.

If you do all the above and still get Protect, then there is a real fault.

In that case the unit may be disassembled and tested to find the fault.

If
that is the case I suggest contacting the manufacturer at the number
listed on the owners manual, or asking a quote on repair to a local
technician.

If it is in protect mode then you have a short in your system. A blown speaker will cause it to go into protect mode, also if there are any power supply problems like a loose ground wire or a sketchy connection at the wiring harness it will also trip. My advice is pull the deck check power supply and ground and wiring harness, if it doesnt go away you know its the speakers.It may however need to reset and you will need to unplug the wire bundle from the deck for a moment before getting into the messing with the speakers or wires. Hopefully that cures it so test it and see. Okay if that didnt fix it then you likely have a blown speaker somewhere in the vehicle so get that replaced and rock on.

Protect only comes on when an RCA is grounding out, speaker is blown or
the speaker wires are shorting out. Check all your wiring on the head unit and see if all are insulated with
tape or better and if there's an exposed wire, tape it up. Make sure
that all connections are secured. Then double-check your fuses. Check all of your speakers and their wiring because going into protect
mode is the units way of saying you have a problem with your speakers
or wiring.

If your speakers and wiring all check out, disconnect your radio wiring harness, and then reconnect the harness. This resets your radio, and your radio should be working again.

If you need to enter the security code, try the default unlock code of 5227.

You can also try to reset your code if the default doesn't work. Try 'KCAR' or '3051'.

The reciever will go into protection mode when there is a short in the speaker wires or the amplifier was overloaded. What I would do first is verify that none of the speaker wire connections are loose at the back of the reciever or at each speaker. And verify that none of the wires are making contact with each other. Then label each speaker wire as you remove them from the reciever so you can re-install them correctly. After you have disconnected the speaker wires try unplugging the reciever for 10 to 15 minutes. Most recievers have a self-resetting overload protection switch and this should reset it back to normal. Now try plugging the reciever back in and turn it on without the speaker wires connected. It should be out of protection mode now. If it is still in protection mode verify that there is not a reset switch somewhere on the back of the reciever. If it is not in protection mode now then proceed to connect one speaker set at a time and turn on the reciever to see if it goes into protection mode. If it goes into that mode after connecting a speaker then that speaker is the cause of the problem. If it does not go into the mode after all speakers are connected then try turning the volume up. If it goes into protection mode then there could be an internal short on the amplifier or a incorrect OHM rated speakers connected to reciever. Verify that the speakers are rated the correct OHMS.

protect mode means some speaker wires somewhere in the car are grounded out or are crossed... find the short and it will fix the problem. try testing all of the speakers one by one from the wiring harness... you'll find the problem. Good luck.
